Conclusion
Tracheal diverticula are rare,
with an estimated frequency of 1% by autopsy and 0.75-5.2% with computed tomography.
Acquired diverticula has been associated with persistent chronic cough by increasing intraluminal pressure in the trachea,
resulting in a mucosal herniation through a weakness area of the tracheal muscular wall.
Our study demonstrated there is no association between closed and direct trauma (cough) on tracheal epithelium in the development of tracheal diverticula.
Despite the slightest difference between the two groups,
tracheal diverticula were more frequent in the trauma group (5.6%) compared with respiratory symptoms group (4.4%).
Differential diagnoses of paratracheal air-filled lesions include lymphoepithelial cysts,
bronchogenic cysts,
laryngocele,
pharyngocele,
Zenker’s diverticulum,
and abnormalities of the third and fourth branchial arch.
Bronchoscopy provides definitive diagnosis,
however diverticula with narrow neck may not been seen.
The treatment options varies depending on the literature between surgical resection,
fulguration,
endoscopic cauterization with electrocoagulation and conservative treatment with medical management of symptoms.
Chest trauma was not associated with the formation of trachea diverticula.
Chronic cough was associated with the development of tracheal diverticula due to the increased pressure in the tracheal epithelium.
The right side of the tracheal wall was more often affected than the left side,
probably related to the support function of the left paratracheal structures of the tracheal wall.
